Azure Devops : unauthorized: authentication required,-CodePudding

need some help. I created a custom image that pushes to Azure Container Registry and use it as a based image for the Azure DevOps pipeline, but it seems it does not pull the image.

azure-pipelines.yml

jobs:
- job: rf
  container:
    image: test.net/rethrf:8944

Output

Error response from daemon: Head "https://test.net/v2/rethrf/manifests/8944": unauthorized: authentication required, visit https://aka.ms/acr/authorization for more information.
##[warning]Docker pull failed with exit code 1, back off 2.89 seconds before retry.

any solution to this? or did I miss any environment variables?

CodePudding user response：

you need to add a service connection since you are communicating with the other azure services.
you can add service connection in portal it is under the project settings.

Select service connection and after that popup will appear on which you have to select docker registry
Fill the subsequent form about the subscription and ACR details
Another approach would be to use docker to pull images

Refer this documentation about it.
